IMPORTANT NOTES  
In addition to the items listed under “IMPORTANT SAFETY INSTRUCTIONS” and “USING THE UNIT SAFELY”  
on pages 2–4, please read and observe the following:  
Power Supply  
Maintenance  
301  
401a  
Do not use this unit on the same power circuit with any  
device that will generate line noise (such as an electric  
motor or variable lighting system).  
For everyday cleaning wipe the unit with a soft, dry cloth  
or one that has been slightly dampened with water. To  
remove stubborn dirt, use a cloth impregnated with a  
mild, non-abrasive detergent. Afterwards, be sure to  
wipe the unit thoroughly with a soft, dry cloth.  
307  
Before connecting this unit to other devices, turn off the  
power to all units. This will help prevent malfunctions  
and/or damage to speakers or other devices.  
402  
Never use benzine, thinners, alcohol or solvents of any  
kind, to avoid the possibility of discoloration and/or  
deformation.  
(add)  
For routine care of the carpeted area, use a brush with  
stiff bristles.  
Placement  
351  
Using the unit near power amplifiers (or other equipment  
containing large power transformers) may induce hum.  
To alleviate the problem, change the orientation of this  
unit; or move it farther away from the source of inter-  
ference.  
Additional Precautions  
553  
352  
Use a reasonable amount of care when using the unit’s  
buttons, sliders, or other controls; and when using its  
jacks and connectors. Rough handling can lead to  
malfunctions.  
This device may interfere with radio and television  
reception. Do not use this device in the vicinity of such  
receivers.  
354a  
556  
Do not expose the unit to direct sunlight, place it near  
• When connecting / disconnecting all cables, grasp the  
devices that radiate heat, leave it inside an enclosed  
vehicle, or otherwise subject it to temperature extremes.  
Excessive heat can deform or discolor the unit.  
connector itself—never pull on the cable. This way you  
will avoid causing shorts, or damage to the cable’s  
internal elements.  
355  
To avoid possible breakdown, do not use the unit in a wet  
area, such as an area exposed to rain or other moisture.  
356  
Do not allow rubber, vinyl, or similar materials to remain  
557  
A small amount of heat will radiate from the unit during  
normal operation.

discolor or otherwise harmfully affect the finish.  
357  
volume at reasonable levels. You may prefer to use  
headphones, so you do not need to be concerned about  
those around you (especially when it is late at night).  
559  
Do not put anything that contains water (e.g., flower  
vases) on the piano. Also, avoid the use of insecticides,  
perfumes, alcohol, nail polish, spray cans, etc., near the  
unit. Swiftly wipe away any liquid that spills on the unit  
using a dry, soft cloth.  
When you need to transport the unit, package it in the  
box (including padding) that it came in, if possible.  
Otherwise, you will need to use equivalent packaging  
materials.  
During operation, this device must be placed at a  
distance of no less than 50 cm from any walls.  
At least two persons are required in order to safely lift the  
unit when it is to be moved.  
Do not allow objects to remain on top of the unit.

Introduction  
Main Features  
MEMO  
What’s FFP (Feed Forward Processing) Technology?  
-
Thanks to FFP technology, this DSP (Digital Signal  
Processing) bass amplifier offers superior performance  
regardless of its compact and lightweight body.  
FFP is innovative technology from Roland that predicts how  
to obtain optimal operation for the amplifier, cabinet,  
speaker, and respective input signals that make up the bass  
amp system. By performing signal processing based on these  
predictions, it obtains maximum performance from each of  
these components.  
-
Benefits of FFP Technology  
1) FFP technology makes it possible to achieve dynamic,  
high-powered sound that surpasses the output spec.  
The Power Injection indicator allows you to monitor  
the effect.  
2) Although the cabinet is compact, the unit is able to  
deliver a truly powerful low end, far out of proportion  
to its size.  
MEMO  
What’s COSM (Composite Object Sound Modeling)  
Technology?  
3) You can obtain clear sound with excellent response.  
Technology that uses different means to create a virtual  
reconstruction of physical structures, materials, and so on  
that actually exist is called modeling technology. COSM is  
proprietary technology from Roland that combines several  
kinds of sound-modeling technology to create even newer  
sounds.  
-
-
You can store the settings for controls in memory A or  
memory B (Memory feature). It’s also possible to call up  
the contents of memory with a foot switch. This means  
you can also change amp settings quickly during live  
performances.  
The amplifier section employs COSM technology, which  
uses modeling to re-create sound characteristics  
originating in differences in amplification systems and  
circuit design. This makes it possible for you to obtain  
everything from high-response, wide-ranging sounds to  
overdriven sounds. The Compression feature even  
replicates the unique compression characteristics of amps  
through modeling.  
Before You Use the DB-700  
When you want to use the amplifier like a conventional  
analog amp or want to play sounds using the present control  
settings, such as when you’ve adjusted the controls to new  
settings, press the MANUAL button to make the indicator  
light up.  
-
-
The amp is equipped with a three-band equalizer offering  
easy operability. Because the midrange-band frequencies  
can be changed, you can create a wide range of sounds.  
You can also use it in combination with the Shape switch  
to obtain a rich variety of sounds.  
The factory-default control settings are stored in memory A  
first time after purchase, the sounds play according to the  
settings in memory A, regardless of the present control  
settings.  
This amp features a newly developed D-chorus that has  
been specially tuned for bass. Dynamic band-division  
processing is performed as appropriate for the input  
signal, to produce a great chorus effect that does not  
impair the low-frequency response even when you use  
"slap" playing techniques or when you play harmonics.  
After that, starting with the next time you turn on the  
NOTE  
power, sounds are played with the settings in effect  
when the power was last switched off. For instance, if  
you turn off the power while the settings in memory A  
are in effect, sounds are played using the settings in  
memory A the next time you turn on the power.  
-
The input and output connectors include a headphones  
jack with optimized tonal correction, a high-performance  
XLR-type DI connector, two types of Line Out jacks (an  
XLR type and a balanced phone jack), and convenient  
Insert jacks for connecting external effects units or other  
equipment, thus providing support for a wide variety of  
applications.

How to handle the Casters  
Attaching and Removing the Casters  
You can attach or remove casters as shown in the following figure.  
Be sure to remove all casters when accidental movement may be dangerous such as when setting up the DB-700 on stage or  
when transporting it in a vehicle.  
If casters have been attached to the amp, make sure it is used only on a stable, level surface.  
Attaching all of the casters can make it easier to move the amplifier.  
(Usage Examples)  
You can use the DB-700 as a floor monitor by removing the two wheels on the rear-panel side and setting the amplifier at an  
angle. (Be sure it remains stable when you do so.)
